When beginning research in a foreign country, it is imperative to know and understand the type of legal system or systems that operate in the country.  Most but not all Latin American jurisdictions have a legal system based in civil law, but each country within Latin America has a wholly unique legal system. The civil law countries of Latin America simply share a “family resemblance” in that many evolved from the Spanish and the Portuguese yet “they do not have a common essence, but rather interrelate with each other in a complex manner.” [ [1] ] Therefore, you should always consult a research guide to understand each country’s legal system.

Researching the law in a civil law system often requires digging into the codes and related commentary and doctrine. It is often helpful to examine a relevant and authoritative secondary source such as a legal encyclopedia, law journal article, or book, which will often cite the primary law (constitution, legislation/laws/codes (with commentary), judicial opinions (caution!).  Remember, judicial decisions in civil law jurisdictions are generally not precedent as they are in common law jurisdictions.

This research guide focuses on online resources.  It will help you find research guides and tools to help you begin your research and familiarize yourself with a country’s legal system.  It will also assist you in locating secondary resources and primary law. This research guide does not list websites for individual countries – please see the Country-by-Country Guide to Foreign Law Research and individual country research guides in GlobaLex for this specific information.
